So with some less-than-gentle persuasion with a rubber mallet, I got the heads off my 1.7 core.
This engine didn't turn over and it's obvious why...the cylinders have rust on the inside and the pistons will not budge. I need to get the Ps and Cs off and I don't care if I damage them as they're toast anyway, but I need to keep the case pristine as this is what I'll be using for my rebuild (really it's why I bought the core). So, any tricks to free up and remove the pistons and cylinders? More persuasion with a rubber mallet? Gallons of PB blaster? Mild explosive? |
